General outline of operation-fit the outset of the description ci my improved ma 'chine I shall set forth in a general way the fue S2 object which it accomplishes and the opera.

tions whichit performs; in order that the den tailed description ci" the mechanical contrivances which is to follow can he more readily q understood. My machine is designed for sealing 'the ends of cartons' ci the type formed ci tubular blank with ioni' flaps at each end. nished to users thereof with the longitudinal seam hetwe'en'the meeting edges oi' the pasteboard alreadyY sealed the edges marked by scoring and the entire structure folded into iat shape. The user ci' these cai tons must necessarily fold and glue the het tom iiaps of the cartons, then fill them r"Fliese blanks are uri iso 'with the material whichthey are eventually tocontain aid then seal the top flaps to incluse the material. t has heretofore been customary in the majority of carton sealing machines to seal either tie tops or the bot, tom on a single machine, but my improved machine provides fac the top and bottom flaps of cartons and therefore necessarily contains suitable holdinsn ifreans for cartons in their original condition with both top and bottom flaps profleeting upward and downward and also for cartons after the bottoms have been, sealed land material has been placed within the cartons.

nmy machine l provide an endless'conveyer which carries a series of blocks ada-ptcd; to hold the cartons in their original con'- dition and also a series of filled carton holders adapted to hold cartons after the bottoms have been sealed with material. These tivo types of carton holders are arranged'alternately upon the conveyer. The cartons in thei original condition are slipped-over the blocksby hand in the usual 'way and removed by hand or by compressed air after the sealing operation is completed, the operative or operatives who perform this work ending between. the point ofentrance trie point of enit of the series of cartons. Except for the florence in the manner in which the cartons are placed. upon or in the carriers th iilied cart iis and cartons whose bottoms re to he sealed are treated in erractl'v the saine way shall, thereforev ce. 1v future descriptions of the general of 'he :nel e to operation understood that be veen e two iilled carton carriers is Vgalilei-ail a loloelr upon which cartons may be 'lr/ed at will. for the purpose of having i .cir lbottom folded and sealedp y The filled cartons 1ere placed upon fa suitable conveyor belt and are thereby brought to the machinewhere they are engaged sucoessively hy a suitable .feeding device, which J' device operates to force the cartons 'e holders the: efor which are carried as aforesaid by the endless conveyer.' lt will he understood that this feeding device ,is timed so'as to operate only when the eartn holders for filled cartons are in position l' vreceive the same so 'that when a carton crear piece ,sindone side, a `suitable eenropcrs heidi Levies is brought into acand the carton holderis then carried y e endless conveyer about a sprocketan. .l-cam-\vheel and dining-g" movement around the same is first engage hy rear lap'holder carried by an erro i the center of sind A- ies sealing bothA them apart and one vdone hy a stationary i .vestire feed belt it immediately'enters one sprocket-and-cam-wheel so that the holder moves with and substantially at the same speed as the carton and While following it in this manner isswung down to engage the ,rear flap of the carton and fold it down into placen Immediately after this flap is thus folded the carton, still continuing its course around the sprocket-andcamwheel engages with its front edge a stationary front flap folder which forces the front flap down over the rear flap. Immediately after this action the two side aps are engaged by a suitable 4delecting devicel which spreads of the side flaps passes between twol glued rollers so as to receive glue both on its inner and outer, or its lower and upper surfaces. The application of glue to this flap in this manner occurs just after the carton has passed from the periphery of the cam and sprocket wheel, and is traveling in a straight `course with the endless conveyer. As the carton moves on the glued flap engages thestationary defiectorwhich gradually turns it up from a substantially horizontal position to the outside into a position substantially vertical or inclined endward to a slight eX- tent. It will be understood that no true folding action is performed by this guide, its only action being to raise the flap into position to be acted upon by a suitable folder. l call particular attentionto this feature because it has been found in the use of carton machines that any actual folding folder which slides along the flap has a tendency xto twist the flap and produce an inaccurate fold.

After the glued .flap of the carton is turned up as aforesaid the carton holder is carried by the endless conveyor around a portion of the periphery of'a second wheel which said sprocket wheel carries a plurality of radially movable side flap folders. lt-is obvious that while the carton is mov-` ing about the periphery of this wheel the side flap folders which are Kcarried by the.' wheel, will have no relative movement with respect to the cartons in a-longitildinaldirection. Immediately after the carton `begins to follow the periphery of this sproeliretw wheel one of the side flap folders isfprojected radially outward and encounters the glued flap folding it'- down upon the front flap and the rear flap which have already been acted upon as set forth. The side fla holder is then immediately retracted but 1s followed up by a second flap folder whic'h is mounted upon an arm which runs about the center of rotation of said second sprocket- 'wheel and provided with mechanism, whereby it can Ibe reaiprocated along said arm. This secondsidc flap folder contacts witli the second side flap of the carton and immediately folds it down upon the first side Hap" so as to engage the-upper glued surface thereof. 'l`his secondI side flap folder 1501-'` ries lows the carton until it has substantially iinished its traverse of the periphery of said second sprocket-wheel, at which time the said side ap is retracted and returned into position to act upon the next carton. he carton then passes under a small squaring roller having a right-angled groove in its periphery, which groove trucs 'up the last fold and the carton holder then passes about the periphery or a portion of it of a third and larger sprocket-wheel. During the -course of this movement the carton passes` under a series `of heavy conical rollers which press the glued aps firmly together vand holds them together until the glue hasset. The carton passes out from under the last roller or' the series just as it completes its traversel ol the periphery of said third sprocket-wheel and at this point, by a suitable cam, the carton clamping device oi' the carton holder is released. Immediately thereafter an ejector carried by the carton holder is operated and this ejector pushes the carton from the holder into a suitable discharge trough. As before stated the operation for cartons whose bottoms are to be sealed is exactly the same in all particulars except that they `are placed upon the blocks by hand and are removed b vhand. The

cartons carried by these blocks pass around all three sprocket-wheels and have their side flaps operated upon in exactly the same Way as do the cartons whose progress has already been set forth.

Having this general description of the operation of my machine and the general purpose of the various parts thereof, l shall now set forth thel details of construction by which operative mechanism-,for producing these various results are secured. Certain parts of the structure can be very greatly modified if desired without departing from the spirit of my invention, while other parts are perhaps shown in the best embodiment for producing satisfactory results. Therefore, while l shall set forth ,with the greatest detail the actual construction of my machine, l fully realize that it can be modified and l do not intend to limit myself by such accuracy of description except as I shall hereafter point out in the claims wherein the particular features of my invention reside.

Frame and sftfftng.-Referring to the drawings, A is the frame of my machine,-

which may be constructed in any desired forni and ci' any material suitable for supporting the working parts, although,l l pre- Jfer to vloria the same'substantia-lly as illustrated in the drawings and in a Arectangular form with longitudinal and transverse bars connecting the corners both at the top and at'` a point a short distance from the bottom of the frame. y

A1 is the main driving shaft of my inach'ine, the same being provided with tight A and loose pulleys adapted to be connected with any suitable source of power. The niain driving;- shaft A1, which is normally kept in. continuous rotation, is connected by suitable miter gears with a glue-wheel drivesha't A2, extending in a vertical direction at the rear end of the machine.

A is a shalt in line with the shaft A1 and adapted to beA connected therewith by means ot' a clutch o2 which can loe operated by .means of a hand-lever a3, connecting therewith links ai.

A* is a vertical drive-shaft driven from the shaft A3 by means of e. transmission shaft A provided Ywith miter gears which mesh with corresponding gears on the shafts A4 and A3 respectively. The vertical driveshaft A? imparts motion to all the operating parts of the device excepting the glue- Wheel so that when the clutch or) is disconnected the entire movement of the 'machine Will cease. l drive the glue-wheel from 'the continuously rotating main drive-shaft A1 because, owing to the 'viscous nature of the glue, the glue-wheel should be kept in practically continual motion to prevent clogging and drymg of the glue on its,suriace.

Unimog/cr chain and its fictief-listening `now to Fig. 8, B is a conveyor chain run-t of the machine. "ll conveyer idler, how! ever, is of smaller diameter than the main conveyor sprocket C and' between these sproclietsvand at the rear of the machine is an intermediate conveyor idler E mounted upon a vertical shaft El also supported by the frame of the machine. it will be seen that the chain B runs outside the main con-I veyor/sprocket C and the conveyor idler D, these two wheels beinginclosed by the curvo of the chain, while the. intermediate con-- veyer idler E lies outside of the curve of the chain bending the same into a reverse curve as illustrated.

B1 are the blocks carried hy the chain ll and adapted to receive the cartons whose bottom laps are to he folded. Theseblocks require no particular description at the present time except to point out that'each one has at its lower end' a plate .7; which is adapted to be engaged by and run in suitable guiding devices `which will be hereinafter set forth.
